Abstract

See full text

A measuring apparatus and a method for determining the degree of bacterial contamination of process liquids uses at least one gas sensor for measuring the gas concentration of a gas producible by aerobic bacteria in the process liquid. An evaluating device is connected with the sensor for evaluating a sensor signal generated by the sensor and correlated with the degree of bacterial contamination. To determine the degree of bacterial contamination a funnel-shaped gas collecting bell is partly immersed in the process liquid so that a gas collection cavity for collection of the escaping gas is formed directly above the process liquid surface in the gas collecting bell. The gas escaping can be fed by a gas pump via a gas feed line to the sensor, conducted via the sensor and pumped back again to the gas collection cavity by way of a gas return line.
